Consider the graph of the line of best fit, y = 0.5x + 1, and the given data points.
Olenka [21]

Answer:

<em>The residual value when x=2 is </em><em>-1</em>

Step-by-step explanation:

The difference between the observed value of the dependent variable and the predicted value is called the residual (e). Every data point has one residual. Lesser the residual value, better the best fit line is.

Mathematically,

e = y-\hat y

Here from the graph,

the observed value is 2, so y=1

the predicted value is 0.5(2)+1 = 1+1 = 2, so \hat y=2

Putting the values,

e = 1-2=-1

creativ13 [48]

Answer:

  • 8 - 42x - 56y - 12xy

Step-by-step explanation:

<u>Given sides of a rectangle</u>

  • Length: l =4 − 7(3x + 4y)
  • Width: w = 3x(−2y)

<u>Perimeter of rectangle</u>

  • P = 2(l + w)

<u>Using the given values</u>

  • P = 2( 4- 7(3x + 4y) + 3x(-2y)) =
  • 2( 4 - 21x - 28y - 6xy) =
  • 8 - 42x - 56y - 12xy

What is the negative root of 2x^2 + x − 6 = 0
max2010maxim [7]
Hello! 

Here we can use the quad formula to solve for the x values or roots.
x=(-2+or - \sqrt{2^2-4*2*-6})/2*2 = -2 and 3/2
The negative root for this equation is x=-2

We find the roots of an equation by solving for x by different ways, most common ones being the quadratic formula of x= [-b +/-sqrt(b^2-4ac)]/2a or factoring and setting equal to zero and solving for x value(s) that way. Also the roots are where the graph of the equation crosses the x-axis.



Hope this helps. Any questions please just ask. Thank you kindly
